House sparrows typically lay their eggs from early May through late September. This extended breeding season allows these adaptable birds to raise multiple broods within a single year.
During this period, female sparrows will lay a new clutch of eggs after their previous brood has fledged. The number of eggs laid, known as the clutch size, can vary, but usually consists of about 5 eggs. Once laid, the eggs undergo an incubation period, which typically lasts around 11 days, though it can extend to 14 days in colder environments.
